Abstract: 764,384. Automatic frequency control. HAZELTINE CORPORATION. Feb. 25, 1955 [March 31, 1954], No. 5731/55. Class 38 (4). [Also in Group XL (c)] In a circuit in which the emitter-base path of a transistor is biased in the forward direction and base-collector in reverse direction to provide a reactance, i.e. capacitance between the base 14 and collector 13, a control voltage 22 is applied in the base-emitter path to vary the magnitude of the capacitance which appears between the emitter and collector. The control voltage may be the unidirectional voltage of an automatic frequency control system. Alternatively, the control voltage may vary the mean operating frequency of an amplifier or control its pass band. The control voltage 22 varies the thickness of the layer at the junction 13, 14 and it is stated that if the magnitude of the variation is made small compared with the bias source 20 the modulation is linear. Inductors 21, 23 present a high impedance to R.F. from the generator 29, capacitor 40 by-passing these oscillations. The collector lead includes a lowfrequency inductor 33 shunted by a resistor 32, but the former may be omitted. Where a very high input impedance is required for the source 22, a grounded collector may be used, Fig. 3 (not shown). In a modification, Fig. 4 (not shown), the control voltage is applied to the emitter, the base being connected through inductor 21 to earth.

Filed: 1923-02-28
Abstract: 216,579. Jackson, W. J. Mellersh-, (Koppers Co.). Feb. 28, 1923. Coke ovens.-In a coke oven battery of the kind described in Specification 171,117, the cross connections between the heating-walls on opposite sides of alternate ovens are arranged beneath the ovens. As shown in connection with an oven adapted to be heated either by rich or poor gas, and having regenerators 18 beneath and parallel to the ovens, the heating flues 17 are arranged in pairs, the two flues of each pair being separated by a partition 25 in which are conduits 27 connected at their lower ends to a cross flue 28 in communication with the corresponding conduits 27 at the opposite side of the oven. In operation, combustion is effected in the flues 17 at one side and the products pass downwards through the conduits 27, beneath the oven through the cross flues 28, upwards through the conduits 27 at the opposite side of the oven, and finally downwards through the flues 17 to the regenerators, the direction of flow being reversed at intervals in the usual manner. At the upper ends of the flues 27 are damper blocks 29 accessible through inspection openings 30. Each heating flue is connected to a pair of regenerators 18, and when operating with producer gas one regenerator of each inflow pair heats the air for combustion and the other the gas. When coke oven gas, supplied through conduits 32 beneath the heating walls is used, both regenerators of a pair may heat the air, or, alternatively, one may be employed for air, while a diluent gas, such as waste combustion products, may be supplied through the other. In a modification in which the regenerators correspond in number with the heating walls, each regenerator is in communication with two walls, the flues 17 of which are not connected by the cross flues 28. In both forms the regenerators and gas supply flues are divided along the longitudinal median plane of the battery, so that the heating arrangements for the ram side are separate and distinct from those of the coke side.
